Thanks for your quick reply. The question now is how to add a EJB Ref to that namespace (java:comp.ejb3). I have 2 EJBs: myEjb1 and myEjb2. The myEjb1 has a ref to myEJB2 like this: | <?xml version="1.0" encoding="UTF-8"?> | <jboss xmlns="http://java.sun.com/xml/ns/javaee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://www.jboss.org/j2ee/schema/jboss_5_0.xsd" | version="3.0"> | | <enterprise-beans> | <session> | <ejb-name>MyBean1</ejb-name> | <local-jndi-name>ejb/myEJB1</local-jndi-name> | <ejb-local-ref> | <ejb-ref-name>ejb/myEJB2</ejb-ref-name> | <local-jndi-name>ejb/myEJB2</local-jndi-name> | </ejb-local-ref> | </session> | </enterprise-beans> | <resource-managers></resource-managers> | </jboss> | | And the MyBean2 binds to the JNDI name 'ejb/myEJB2'. When I deploy both EJBs in a EAR file to JBoss 4.0.4GA/EJB3.0, I get the exception: | javax.naming.NamingException: Could not bind statless proxy with ejb name MyBean1 into JNDI under jndiName: /ejb/myEJB2 [Root exception is javax.naming.NameAlreadyBoundException] | And in the JNDIView, it shows that the MyBean2 was already bound to 'ejb/myEJB2'. I don't understand why. Thank you View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3968381#...
